I only got one TV in my ML system (LX5500). I've now moved it down to the basement (in Swedish: till Gillestugan). The BS9000 is still upstairs in the living room. To listen to one of them using the other I must use the command [AV]. Is it possible to set them both to option 2 so I just can press [RADIO] to listen to radio through the LX, and [DTV] on the BS etc.?

Set BSD 9000 to "A.Opt" "2" or "STANDBY"  "SOUND" "2" "STORE" with a BeoLink 1000 

If the LX is still the main tv of your system (connected via BeoLink-Converter to the ML-System)
set it to "V.OPT 2.5"

Easily done with a BeoLink 1000 by pressing:

"STANDBY"  "PICTURE" "2" "STORE" and then "PICTURE" "5" "STORE"

Great! Works perfect! Many thanks!
